Concepts: In my Explain Everything presentation I learned that yeast is a micro-organism and they are fungus consisting oval cells, this would considered as the concept of function. Following up, if the dough is in a metal tin it causes the dough to rise upwards, the carbon dioxide gives it air. Our responsibility when dealing with yeast is to wash our hands before and after. Yeast can be used in lots of different foods like pizza’s (dough), bread, and some more. One things I can work on next time when doing an Explain Everything is to make sure when people are reading it they can see all the words because some got a little cut off at the end. Another, is to add pictures to what I am talking about so the reader can see an image on what it should look like if they were watching someone make dough for the fresh bread.
